- Ball top size (bond formula): calculation of the top size grinding media (balls or cylpebs):-Modification of the Ball Charge: This calculator analyses the granulometry of the material inside the mill and proposes a modification of the ball charge in order to improve the mill efficiency:
Calculate and Select Ball Mill Ball Size for Optimum Grinding
Calculate and Select Ball Mill Ball Size for Optimum Grinding. Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^0.5 where D m = the diameter of the single-sized balls in mm.d = the diameter of the largest chunks of ore in the mill feed in mm.
THE GRINDING CHARGE OF ROTARY MILLS
The total wear of grinding media, during the cement clinker (balls of forging steel and hardened with 600 Brinell, and cylpebs by special iron) is of 162 – 308 g/t of cement (4.4 – 8.4 g/kWh) [2]. The presented values show a rapid wear of grinding media, which leads to the diminution of specific charge, with negative effects on grinding process.

Grinding in Ball Mills: Modeling and Process Control
There are three types of grinding media that are commonly used in ball mills: • steel and other metal balls; • metal cylindrical bodies called cylpebs; • ceramic balls with regular or high density. Steel and other metal balls are the most frequently used grinding media with sizes of the balls ranging from 10 to 150 mm in diameter [30].
